This study found that novel thiol-reactive cross-linking agents, particularly APA, significantly improved the tensile strength and elasticity of human hair fibers by effectively regenerating disulfide bridges, with potential applications for advanced hair repair treatments in the cosmetic industry.

This article explores the integration of nanotechnology and cosmetics, highlighting the development of cosmeceuticals targeting issues such as wrinkling, hyperpigmentation, and skin dehydration, while also reviewing cosmetic history and types of nanotechnology by particle size.

In this study, researchers used 3D printing combined with cryogenic crosslinking to develop gelatin/oxidized alginate scaffolds and found that adding 5% hydroxyapatite improved mechanical properties and osteogenic effects, enhancing bone tissue regeneration, though 10% hydroxyapatite offered no additional osteogenic benefits and reduced shape fidelity.

In this study, children's hair showed statistically higher elasticity than elderly hair, but no significant differences were observed in tensile strength between dietary or oil application groups, or between pigmented and nonpigmented hair.

In this review, several studies on Astragalus species, particularly Astragalus membranaceus, highlight their skin rejuvenating, photoprotective, antimicrobial, and wound-healing properties, though the authors note limitations due to reliance on non-human studies and short trial durations.

In this systematic review and meta-analysis, researchers found that exosome therapies significantly improved facial wrinkles by 20.2% and enhanced hair density and thickness by 23.6% and 18%, respectively, despite challenges in generalizability due to study heterogeneity and nonstandardized protocols.

In this study, a 90-day course of a plant-based supplement significantly improved hair density, skin hydration, and nail growth among participants with dermatological concerns, while also reducing hair fall and pigmentation, without adverse effects.

In this narrative review, the authors explored various rehabilitative techniques, including injections and physical therapies, that may enhance aesthetics and psychosocial wellbeing in patients with disabilities, emphasizing a multidisciplinary approach to improve both functional and cosmetic outcomes.

Multi-pass laser skin treatments improved healing, reduced pain, and had no major complications.

This study found that near-infrared LED therapy enhanced ATP synthesis, reduced reactive oxygen species, and promoted collagen production and hair growth more effectively than white LEDs in human skin cells and a photoaging mouse model.

This review suggested that low-level light therapy using red/near-infrared light could be a safe and effective treatment for various skin and hair conditions, though more robust trials are needed to solidify its clinical utility.

This review explores the potential of mesenchymal stem cells in skin regeneration and rejuvenation, highlighting their ability to modulate immune response and enhance extracellular matrix strength but does not provide new clinical evidence.

This review summarizes the positive clinical response of using platelet-rich plasma as an adjuvant in skin rejuvenation treatments, with no identifiable complications, suggesting a promising outlook for its future use.

This review found that existing studies on adipose tissue for scarring, wound healing, and hair growth show some positive outcomes, but the evidence is insufficient to change current dermatological practices.

This article reviews common dermatologic procedures, focusing on skin biopsy techniques, with no new clinical results reported.

This review discusses emerging concepts in PCOS from the AEPCOS 2010 meeting and reports no clinical findings; it suggests that the transition of care in congenital adrenal hyperplasia could inform PCOS adolescent care.

This case report describes a dual transposition flap technique for closing large scalp defects post-Mohs surgery, achieving minimal alopecia and scar visibility, though it is based on a single patient.

This review discusses the relationship between estrogen deficiency and skin aging in postmenopausal women, noting potential benefits of estrogen use on skin collagen and elasticity, but reports no new clinical results.

This review discusses advancements in techniques for scalp reconstruction, highlighting improved cosmetic outcomes and reduced morbidity, but reports no new clinical results.

This abstract reviews the characteristics and health risks associated with polycystic ovary syndrome and does not report new findings, highlighting the syndrome's multifactorial nature.

This review indicates that estrogen loss during menopause significantly impacts skin health, while estrogen treatment may increase skin collagen, thickness, and elasticity, though effects on other skin characteristics are inconsistent.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This review discusses the effects of oestrogen on skin ageing and highlights the need for large-scale clinical trials to evaluate postmenopausal oestrogen use, reporting no new findings.

This review examines non-invasive methods for diagnosing inflammatory skin diseases like lupus erythematosus and psoriatic inflammation using samples from plucked hair and skin tape-strips, but no new clinical results are presented.

This study concludes that egg shell membrane hydrolysates, particularly Fraction I, may effectively mitigate UV-B radiation-induced wrinkles and promote skin collagen and hyaluronic acid production, suggesting potential use in functional cosmetics.

This review focuses on the roles of amino acids, peptides, and proteins in cosmetics, highlighting their importance in skin health and their potential for development in personal care products due to their unique properties and biocompatibility.

This review highlights that castor oil has potential dermatological uses, including enhancing hair luster, reducing hyperpigmentation, and improving skin hydration and elasticity, although rare side effects like contact dermatitis occur, necessitating further research to confirm its effectiveness in these applications.

This study revealed that during avian skin development, complex tissue architecture results from specific cellular flows and mechanical processes that guide feather bud protrusion and elongation, with distinct differences noted in scale development, where rigidity restricts such transformations.

This study found that intradermal bleomycin injections induced dermal fibrosis in C57BL/6 mice, evidenced by hair follicle obliteration and dermal thickening, though no significant trends in gene expression were observed, indicating the need for further research to understand the link between fibrosis and dyschromia.

EFBL offers hidden incisions, faster recovery, and fewer risks, but may raise hairline and cost more.
